DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSReferring to FIGS. 1-5, where a first embodiment of a toy hoop 10 of the present invention is shown for use by a person 12. In this embodiment, the toy hoop 10 comprises a hoop member 14 having an annular wall 13, an outside surface 15, an inside surface 17, first and second end portions 16 and 18 and a first channel 20 adapted to receive flow of a first medium 22 such as water. In the embodiment shown, the hoop member 14 is elongated. The toy hoop 10 further comprises an interconnect member 24 having first and second end portions 26 and 28 adapted to connect the first and second end portions 16 and 18 of the hoop member 14. The interconnect member 24 comprises a first channel 30 in communication with the first channel 20 of the hoop member 14 to allow the first medium 22 to flow there thru. Each of the first and second end portions 26 and 28 of the interconnect member 24 have an outside surface 32 and an inside surface 34. The inside surfaces 34 are downwardly or inwardly tapered from a point inward of the first channel 30 to the first and second end portions 26 and 28 to provide laminar flow of the first medium 22 thru the first channel 20 of the hoop member 14. The outside surface 32 may be curved or otherwise shaped to the contour of the inside surface of the first and second end portions 16 and 18 of the hoop member 14 to further reduce friction and head loss. The toy hoop 10 further comprises a first inlet port 36 in communication the first channel 20 to allow the person 12 to adjust the volume of the first medium 22 and therefore the mass of the hoop member 14 and the generated centrifugal force. The first inlet port 36 has an opening 35 formed in the annular wall 13 and extending from the outside surface 15 to the inside surface 17. The first inlet portion 36 further comprises a recessed seat 37. The first inlet port 36 is disposed below the outside surface 15 of the hoop member 14 so that no portion of the first inlet port 36 protrudes outward from the outside surface 15. The toy hoop 10 further comprises a first plug member 38 adapted to engage with the first inlet port 36 to seal the first channel 20. The first plug member 38 generally comprises a one-piece unitary rubber body having a top portion 39 and a bottom or seal portion 41 that engages with the recessed seat 37 to seal the first channel 20. The first plug member 38 made by a wide variety of materials, designs and may be made by a wide variety of processes, including molding. To avoid injury and enhance operation, it is important that no portion of the first inlet port 36 and the first plug member 38 extend outward from the outside surface 15 of the hoop member 14. The first plug member 38 may comprise one or more threads 43 to engage with a thread portion 45 of the first inlet port 36. In use, the person 12 may fill the first channel 20 of the hoop member 14 with a desired volume of first medium 22 to obtain a desired mass, and centrifugal force and sound when used by the person. The first medium 22 may be any type of medium that increases the mass of the hoop member 14 and/or creates a sound when used by the person 12. By way of example only, such medium may include, alone or in combination, water, sand, bells, other objects and incompressible fluids and/or gases. By way of further example only, the first medium may be a combination of water and neon particles which upon use of the transparent hoop member 14 would result in the creation of a centrifugal force and emitted light when used by the person 12.
Referring to FIGS. 6 and 8, wherein another embodiment of the present invention, the hoop member 14 further comprises a second channel 40 formed by a wall 47 and adapted to receive flow of a second medium 42, such as water. The interconnect member 24 comprises a second channel 44 of similar design to the first channel 30 and in communication with the second channel 40 of the hoop member 14 to allow the second medium 42 to flow there thru. The toy hoop 10 further comprises a second inlet port 46 in communication the second channel 40 to allow the person 12 to adjust the volume of the second medium 42. The toy hoop 10 further comprises a second plug member 48 adapted to engage with the second inlet port member 46 to seal the second channel 40. The hoop member 14 and the first and second channels 20 and 40 of the hoop member 14 may be cylindrical shaped. The first channel 20 may be spaced closer to the outside surface 15 of the hoop member 14 then the second channel 40. In use, the person 12 may fill the first and/or second channels 20 and 40 of the hoop member 14 with a desired volume of first and second medium 22 and 42, respectively, to obtain a desired mass and centrifugal force when used by the person 12. The first and second mediums 22 and 42 may be any type of medium that increases the mass of the hoop member 14 and/or which creates one or more sounds when used by the person 12. By way of example only, the first and second mediums 22 and 42 may include, alone or in combination, water, sand, bells, other objects and incompressible fluids and/or gases. By way of example only, the first medium 22 could be water and the second medium 42 could be bells. By way of further example only, the first medium 22 could be bells having a certain tone or sound and the second medium could be bells having a different tone or sound.
Referring to FIG. 7, wherein another embodiment of the present invention, the hoop member 14 may comprise third and fourth channels 50 and 52 formed by walls 51 and 53 and adapted to receive flow of third and fourth mediums 54 and 56. The toy hoop 10 may further comprise third and fourth inlet ports 58 and 60 in communication with the third and fourth channels 50 and 52 of the hoop member 14 to allow the person to adjust the volume of the third and fourth mediums 54 and 56. The interconnect member 24 may comprise third and fourth channels 62 and 64 in communication the third and fourth channels 50 and 52 of the hoop member 14. The first and second mediums 22 and 42 and the third and fourth mediums 54 and 56 may be any type of medium that increases the mass of the hoop member 14 and/or which creates one or more sounds when used by the person 12. By way of example only, the first and second mediums 22 and 42 may include, alone or in combination, water, sand, bells, other objects and incompressible fluids and/or gases. By way of example only, the first medium 22 could be water, the second medium 42 could be bells having a certain tone or sound, the third medium could be bells having a different tone or sound than the second medium, and the fourth medium could be bells having a different tone or sound then the second or third mediums. The hoop member 14 may include one or more drain ports (not shown) to drain the mediums.
The hoop member 14 and the interconnect member 24 are each preferably made from extruded polyethylene (PE) and cut to form a pre-defined shape and size. The pre-defined shape of the hoop member 14 is inserted into a lower mold cavity along with the interconnect member 24 connected to the first and second end portions of the hoop member 14. Upon closing of an upper mold with the lower mold, the interconnect member 24 is heat bonded with the first and second end portions of the hoop member 14.
The foregoing description is intended primarily for purposes of illustration. This invention may be embodied in other forms or carried out in other ways without departing from the spirit or scope of the invention. Modifications and variations still falling within the spirit or the scope of the invention will be readily apparent to those of skill in the art.
